IMPROVEMENT IN MAGHINE FOB. SHRINKING TIRE TO ALL WHOM-IT MAY CONCERN:

Be it known that I, D. ELLEXWOOD, Jr., of Garrcttsville, in thecounty of Portage, and State of Ohio, have invented certain new and useful Improvements in Tire-Upsetting Machines;- and I-do hereby declare that the following is'afull and 'complete description 'of 'the construction and operation of the same, reference being had to the accompanying dra-wings, making a part of this specification, in which-'- Figure 1 is a top view of the machine.

Figure 2 Vis a side view of the same.

Figure 3 is a detached section.

Like letters of reference refer to likeparts inthe views.

A, tig. l, is an iron frame, of which B is a yoke placed transversely across .the same near the head o' the machine. lhishead C is provided with un adjustable shoulder, D, and which issecured to the frame .by the thumb-screw E, O11 the outer ond of the fr ame is a deep' flange, F, which, it will be seen, slightly cnrres and conforms in its curvature and height with the shoulder. On the opposite end of the frame is fixed transversely the stay G, in the-armsof which is journalled the screw H, which is both left and right-hauded. Iis a pair of levers, the long arms of which are attached te the screws by means of the nut-s J, and are operated by 'che same, as will hereafter be shown. These levers are not' pivoted to the frame but lic free upon it, and are kept in position by the yoke referred to, which also serves asa fulcrum, against which they act when in operation. The short arm ofthe levers is made in the peculiar shape, as shown at 11,'fig. Q, for the purpose that it may offer noobstructiou tothe space between the shoulder audit-ange, and also for the reception et" the dogs or cams K, which are stronglyvpivoted to the lever, as shown in the drawing.

The operation of this machine is as follows.: The tire to beupset is placed, while hot, between. the shoulder and ilu-nge, as shown in fig. 1, in which L is the tire. First, however, the sections 5 c are removed and the ilangll and shoulder brought so close together as vto 'admit only the thickness of the tire betweexnas shown in Pl. The cams or dogs are then turned by the'handle M so as to bring them to bear against the tire', the sharp corA rugatiens on the face of which prevent them from slipping. p The position of the tire being thus arranged the power is applied by the screw H, which, ou being turned by the hand-wheel, draws the arms of thc levers out ward with a corresponding reverse action of the short arms, which presses against the tire and causes it to shorten between the two c'ams. The backward pressure of the cam is resisted bythe lugs N and flange F;

against which the tire rests; also, the flange in connection with the shoulder prevents the tire from bending or kinking while being upset. i The position of the tire and cams when the process et" upsetting is accomplished is shown in iig. 1. Should the tire be of such a size as to interfere with the working of the screw it may' be placed in the machine in the opposite dire( zien, as shown in fig. 1, in which o is a small tire. lhe sections and c are placed between the shoulder and ange for thepurpose of holding the tire while being acted upon' by the cams and levers. The power is appliedin the s ame way as in the former case and attended by vthe same results.'

By the usc of this machine the tire can be shortened without the trouble of cutting it for that purpose, hence 'much time, labor, and expense are thereby saved; also, it can be shortened to any degree required with equal certainty. 'lhc power applied being `the combination of the screw and lever, and hence very great, heavy tiresnlay be shortened up with ease and'facility, and to a degree and certainty unattained by the old method.

VWhat I claim as myimprovement, and desire to secure by Letters Patent, s'-Y 1. The frame A, yoke B, iange F, in combination with theiadjustable shoulder D, for the purpose and in the manner'spocified. Y A

2. Letters I, cams K, as arranged and operated by the screw H and adjustable nut J, 'in combination with the frame A, shoulder D, flange F, and yoke B, for the purpose and in the manner as set forth.

3. Sections c and b, in combination with the iiange F and shoulder D, 'for the purpose herein set forth.V
